Bei tknown that L JonnBiiuMLn, of Mil= waurkee, in; the-county ofMilwaukee and State ofiWisconsin, have invented: certain new and useful Improvements: in: Haring-Machines, doiherebydteclare that the following is a-full", clear, and exact description: of the invention, which: will enable others skilled in the art to which it appertains tomakeand use the same; refereneebeing had to the accompanydrawings,.wl1ich form a part of this specification, and in which- Figure l-isaperspeetive view of my improved machine for flaring and bending barrehhoops. Fig. 2 is a side view of the same. Fig. 3 is a rear endyiew. Ais: a vertical sectional view on linex 0:, Fig.1;- and Fig. 5 is a similar View on line 3 y, Fig. 2.

Similar letters of reference indicate corre sponding parts in all the figures.

My invention consists in the detailed construction and combination of parts of a machine for flaring one edge of a barrel-hoop, and at the same time bending the hoop, as will be hereinafter more fully described and claimed.

In the accompanying drawings, A represents the frame of my improved machine. A indicates the forward end piece or end block of the same, the said block being provided with a transverse slot or aperture, A, through which the hoop or hoops pass. In the upper part of the forward end of frame A is pivotally secured one end of each of the arms BB, the said arms having j ournaled in the extremities of their upper or forward ends an axle, (J, passing through an aperture in the upper endof a metal block or cross-head, D. Through the lower end of this block D passes a bolt or pivot, E, the extremities of which are journaled in the upper endsof vertical sliding posts E, the lower extremities of which are rigidly secured to the upper side of the flaring-block F, at an equal distance from the center of the same. This block is vmore clearly shown in Fig. 5 of the drawings, having its lower side or face curved to form the segment of a circle, and being recessed longitudinally at- F, so as to leave a flange or rib, F, extending along either side, for the purpose hereinafter specified. In the lower part of the transverse slot or opening A is a metal bed-plate, G, adapted to be adjusted vertically by means of set-screws G G.

H represents the operating-lever, which is ispi'voted one end of a curved metal plate, K,

connected by means of a pivotedlever, L, and pitmen M N to oneend of the: pivot orbolt'I, inthexbent or curved end of the operating-tel verH; 3

The manner in which my improved mac'hine for flaring and bending barrel-h ops-operates is as follows: One end of thehoops is inserted in that end of the slot or aperture A which is ,to the right handin Fig. 3, thebed-plate Gbeing adjusted vertically by means of the setscrews G G, according to the size of the particular hoops being operated upon. By now raising andlowering the operating-lever Hthe flaring-block F will be alternately forced down upon the upper edges of the hoops passing through the transverse slot A, so as to flare or spread the said upper edges, and then raised to allow of the hoops being advanced a little. By constructing the flaring-block with the flanges F", Icause the upper edges of the hoops to be bent perfectly straight,which would not be the case if the lower face of the block were made perfectly smooth. By this arrangement the hoops are also prevented from sticking in the aperture A. The block J and curved metal plate K, through the intervening mechanism previously described, serve to bend or curve the hoops as they issue from the slot A, after having had their upper edges flared, to adapt them to be more readily placed around the barrel.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of my improved machine for flaring and bending hoops will readily be understood without requiring further explanation.

It will be seen that my improved machine is simple in construction, and, being devoid of all complicated parts, is not liable to break or get out of order.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. The combination, in a hoop-flaring machine, of a frame provided at its head or forward end with a transverse slot or opening through which the hoops are passed, a bedplate adjustably secured in the bottom of the said slot or opening,adj usting-screws by which the said plate is vertically adjusted, aflaringblock working in the upper part of the transverse slot or opening, an d provided with flanges upon either edge of its lower curved face, and means or mechanism by which the said block is operated.

' 2. The combination, in a hoop-flaring machine, of a frame provided at its head or forward end with a transverse slot or opening through which the hoops are passed, a bedplate adjustably secured in the bottom of the said opening, adjusting-screws by which the said plate is vertically adjusted, a flaring-block working in the upper part of the transverse slot or opening, and provided with flanges upon either edge of its lower curved face, two vertical sliding posts having their lower ends rigidly secured to the upper side of the flaringblock at an equal distance from either end, and having their upper ends pivotally connected by means of a movable metal block to the forward end of two pivoted weighted arms, ametal block pivotally connecting the vertical posts and the forward ends of the two pivoted weighted arms, two pivoted weighted arms having their forward ends connected to the upper ends of the vertical sliding posts, and a pivoted operating-lever by which the free ends of the said arms are operated, all constructed and combined to operate substantially in the manner and for the purpose shown. and set forth.

3. The combination,with a hoop-flaring machine of the described construction, of a metal block provided with a curved side, and rigidly secured upon one side of the frame of the machine immediately in advance of one end of the transverse slot or opening through which the hoops pass, a curved metal plate hinged at one end to the rear side of one end of the transverse slot or opening, and a pivotedlever and suitable pitmen for connecting the said hinged plate to the end of the main operating-lever, all constructed and arranged to operate substantially in the manner and for the purpose shown and described.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

JOHN BAUMLE.
